Documentation states: NOTE: There must be a correlation between the wake-up enable and interrupt-enable registers. If a GPIO pin has a wake-up configured on it, it must also have the corresponding interrupt enabled (on one of the two interrupt lines). Ensure that this condition is always satisfied by enabling the detection events after enabling the interrupt, and disabling the detection before disabling the interrupt. This ensures interrupt/wakeup events can not happen until both the wakeup and interrupt enables correlate. If we do any clearing, clear between the interrupt enable/disable and trigger setting.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
